' BLANKFOR PAPER BOXES.

SPECIFICATION forming part of Letters Patent No. 422,792, dated March 4,1890.

Application filed December 26, 1889. $eriel N0. 334 967. (No model.)

in blanks for paper boxes, hereinafter fully described and claimed.

Figure 1 is an elevation of the completed blank, and Fig. 2 is aperspective of one end of the box with the flaps partly folded over.

My improved blank consists of a piece of paper which is divided into sixpanels, three,-

of which (marked L, J, and H) are each as wide as two of the sides ofthe box. The other three panels (represented by those parts of the blanklettered K, I, and G) are as wide as the other sides of the box, andtheir relative size to the panels L, J, and H depends upon whether thebox is to be made square or nearly rectangular. As shown .in thedrawings, the panels K, I, and G are narrower than the panels L, J, andH,

The vertical dotted lines indicate the folds between the panels whichare to form the sides. The panels H and Kare formed in the blank justthe length of the box, while all of the other sides G, I, J, and L haveextending flaps formed at their ends, as shown in Fig. 1, (marked A, B,O, and E.)

The ends of the flaps O and E on the two wide panels J and L are creasednear their ends and preferably beveled, as indicated at D and F, to makethem fit readily into position when the box is closed.

The operation of my invention is as follows: By folding the blank on thevertical dotted lines the panels L and J will come opposite each other,as will also the panels K and I, thus forming a rectangular inclosure,while the panel H will fit over the panel L and panel G will lie overthe panel K, thus making two sides of the box consist of two thicknessesand leaving; a space (marked M in Fig. 2) between the panels H and L.The

end flaps A and B are now folded down. The ,flap E is then folded downand its end F in serted between the edge of flaps Aand B and the innerside of J, and then the end is cornpleted by folding down the flap O andinserting its end D in the space M between the panels H and L, asclearly indicated in Fig. 2, thus forming an end of four thicknesses, inwhich the joint is closed at all sides, by which means a much tighterand closer end results than is the case where the blank is made withonly the four panels necessary to form a box, as is the usualconstruction.

WVhat I claim as my invention, and desire to secure by Letters Patent,is

A blank for a paper box, consisting of a piece of paper divided into thepanels G, I, J, and L, having, extended flaps at each end,

and the panels II and K, without flaps and 65 intermediate of the endpanels G and L and the pair of central panels I and J of the blank,substantially as shown and described.
